What is the lock and load hand shake?

The "lock and load" handshake is a gesture often associated with military culture, symbolizing readiness for action. It typically involves a motion akin to loading a firearm, where one person mimics the act of chambering a round while the other reciprocates, often with a fist bump. This handshake conveys a sense of camaraderie and preparedness among individuals, particularly in contexts related to firearms or military service. It's a playful way to express solidarity and readiness for whatever challenges may arise.
